Abstract
A rolling bearing includes a sealing member body, a sealing lip portion of which has a radial edge that is brought into radial contact with an inner ring. The sealing lip portion is bent at a waist portion that is an intermediate portion thereof in a radial direction, so as to form a relief recess in a surface on an outer side relative to a bearing space and an extensive portion extends, in a turned back manner, from the radial edge so as to be inclined relative to an axial direction toward the outer side of the bearing. The sealing lip portion includes a projection that has a tapered shape in which a dimension is reduced toward a tip end side, and a thickness of the waist portion is set within the range of 25% to 75% of a thickness of the tip end of the sealing member body.
